大爆炸
The Inverted Big-Bang
摘要：
我们的宇宙似乎不是凭空产生的，而是从一个奇怪的时空尘埃中产生的。量子几何（圈量子引力）使我们有可能避免我们宇宙的不祥开端，它具有物理上不现实的（即无限的）曲率，极端的温度和能量密度。这可能是对大爆炸的长期追求的解释，甚至可能打开了一扇通往大爆炸之前的时间的窗户：空间本身可能来自早期坍缩的宇宙，它由内而外或反转并开始再次膨胀。- 关键词：圈量子宇宙学，惠勒-德威特方程，奇点，阿沛·阿什特卡，马丁·博约瓦尔德。
英文摘要：
Our universe appears to have been created not out of nothing but from a strange space-time dust. Quantum geometry (loop quantum gravity) makes it possible to avoid the ominous beginning of our universe with its physically unrealistic (i.e. infinite) curvature, extreme temperature, and energy density. This could be the long sought after explanation of the big-bang and perhaps even opens a window into a time before the big-bang: Space itself may have come from an earlier collapsing universe that turned inside out or inverted and began to expand again. - Key words: Loop quantum cosmology, Wheeler-DeWitt equation, singularity, Abhay Ashtekar, Martin Bojowald.
